Kac's conjecture and the algebra of BPS states
Tim Cramer
Let Q be an affine quiver and let be the positive part of the affine Lie algebra associated to Q. We provide a construction of using the semistable ir…

Double Hall algebras and derived equivalences
Tim Cramer
We show that the reduced Drinfeld double of the Ringel-Hall algebra of a hereditary category is invariant under derived equivalences. By associating an explicit isomorphism to a gi…

Heat Kernel Coefficients for Two-Dimensional Schrodinger Operators
Yuri Berest, Tim Cramer, Farkhod Eshmatov
In this note, we compute the Hadamard coefficients of (algebraically) integrable Schrodinger operators in two dimensions. These operators first appeared in [BL] and [B] in connecti…
